من طرف Angular Momentum of a Rigid Body
Angular momentum of a rigid body (Figure 1) can be obtained from the sum of the angular momentums of the particles forming the body:
[1]
Figure 1
where ri = the position vector of particle i, and w = the angular velocity vector of the rigid body. Now, let
Note here that a local reference frame, the XYZ system, is defined and fixed to the body at O and ri & w are described in this frame. Substituting [2] & [3] into [1]:[2]
[3]
[4]
